Escopo e aplicabilidade

This standard applies to the design, manufacturing, and testing of various remote-controlled fire monitor systems. It covers systems categorized by their extinguishing agents, including water, foam, dry powder, compressed air foam, and dual-agent systems. It is applicable to all manufacturers producing fixed firefighting systems for the Chinese market. The standard also governs critical components such as wireless remoters, electric control devices, fire monitor towers, and foam proportioning devices.

Requisitos técnicos

The standard specifies comprehensive performance criteria for system operation and components. It mandates that the system's response time from controller activation to monitor movement must be under 5 seconds, with wired control distances of at least 200m and wireless distances of at least 150m. Manufacturers must ensure reliable and smooth system startup under these control parameters. For wireless remoters, the standard requires an IP67 protection rating, drop resistance, vibration resistance, and low voltage alarm capabilities. Electric control devices must meet strict insulation resistance and dielectric strength requirements. These components must demonstrate robust performance in harsh environmental conditions. The standard outlines specific喷射 (spray) performance parameters for different monitors, including range, flow rate tolerances, and foam expansion ratios. It also sets structural and functional requirements for fire monitor towers, such as mandatory water curtain protection, anti-corrosion treatments, and specific dimensions for rest platforms and guardrails. Compliance with these structural integrity requirements is mandatory for safety certification.

Métodos de ensaio

The standard outlines various testing procedures to verify compliance. Key tests include hydrostatic strength tests for pressure-bearing parts, where components are subjected to 1.5 times the maximum working pressure. Components must show no leakage, cracks, or permanent deformation after these tests. For wireless remoters, tests include water immersion per GB/T 4208-2017, free-fall drop tests from 1.5 meters, and vibration resistance tests following GB/T 2423.10. These rigorous tests ensure the remote's reliability during emergency operations. Additionally, the standard references GB 19156-2019 for喷射 (spray) performance testing of the monitors and GB 6245 for fire pump performance evaluation, ensuring all integrated system components meet national safety benchmarks.

Perguntas frequentes

What products are regulated under GB 19157-2025?

The standard regulates various types of remote-controlled fire monitor systems, including water, foam, dry powder, compressed air foam, and dual-agent systems. It also covers associated components like wireless remoters, electric control devices, fire monitor towers, and foam proportioning devices.

Are there any updates from the previous version of GB 19157?

Yes, the 2025 edition replaces the 2003 version. Key updates include revised terminology, new performance requirements for electroplated parts, updated parameters for electric control devices, and the addition of specific performance requirements for remote-controlled dry powder and compressed air foam systems.

How does GB 19157-2025 differ from other fire protection standards?

GB 19157-2025 is a dedicated national standard focusing specifically on the system-level performance and integration of remote-controlled fire monitor systems. It references several foundational standards like GB 19156-2019 for individual monitor performance and GB 6245 for fire pump specifications.
